What happened
Anthropic launched Project Glasswing with a Claude Mythos Preview that has already surfaced thousands of high-severity zero-days across major operating systems and browsers. Access is limited to ~50 organisations (AWS, Apple, Microsoft, Google, Cisco, NVIDIA, JPMorgan Chase) with up to $100M in Anthropic usage credits.
Why it matters
Represents a structural shift: AI-driven vulnerability discovery now outpaces human experts on foundational software. The gated distribution reflects real dual-use concerns and sets a precedent for AI security capability governance.
Applicability
Critical for software maintainers, security teams evaluating AI-powered vulnerability management, and supply-chain-risk owners.
